TECHNICAL FIELD OF THE INVENTION

This invention is related in general to information transmission systemsand, more particularly, to an information transmission system that isoperable to be stored at a remote location as a secure file in a trustedenvironment.

BACKGROUND OF THE INVENTION

With the popularity of wireless “digital” computing devices, such as,Personal Digital Assistants (PDA's) cell phones, cameras, video, audiorecorders and other digital recorders, users have been afforded theability to record and transmit digital media within seconds.

With the advent of digital media, it has become increasingly easy tocopy, counterfeit, falsify and misuse digital information of all kinds.This includes digital photographs, video & audio recordings of speech ormusical performances, motion pictures and recordings of physicalphenomena, such as meter readings or “black box” records. This digitalmedia can be altered in ways that defy detection, audio recordings canbe compressed and anonymously offered to the public with impunity, andtime and date stamps on any of the media just listed can be easilychanged with freely available tools.

An attendant problem is that of secure storage. While a flash memorycard within these digital recording devices (in any of its currentlypopular forms) can hold hundreds of pictures, images, video and audio,the problem with securely storing, indexing and retrieving thousands ofmedia files has still not been solved. When the works of intellectualproperty (music, software, images and movies, to name a few) are muchmore valuable than the equipment on which they reside, the temptationfor theft and alteration becomes great.

Furthermore, this invention provides for the secure non-repudiation byembedding Certificate Authorities non-repudiation Digital Certificatesof the digital files for forensic or other evidentiary purposes that aresent and received across the transmission networks.

This works for any kind of media file—photographs, images, music, audiospoken word, video, physical phenomena—anything. Obvious applicationsrange from taking a photograph, video clip to “black boxes” embedded intransportation facilities. Following an incident, information could betransmitted using the above schemes to a storage facility. Onlyauthorized personnel could then retrieve the encrypted messages andreturn the data to cleartext form.

SUMMARY OF THE INVENTION

The present invention disclosed and claimed herein, in one aspectthereof, comprises an apparatus for acquiring information to betransmitted to a receiving facility and for transmitting such thereto. Acapture device captures information from a first source. A processor isprovided for associating with the captured information the date and timeof the capture of the information, such that the date and timeinformation in association with the captured information forms augmentedcaptured information. The processor is provided for placing theaugmented captured information in association with subscriberinformation in a transmission of the augmented captured information to areceiving facility requiring such subscriber information. A transmittertransmits the transmission including the augmented captured informationand the subscriber information to the receiving facility. An encryptorencrypts the augmented captured information with a symmetricalencryption algorithm to provide encrypted augmented captured informationin the transmission with the subscriber information.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to FIG. 1, there is illustrated a block diagram of theoverall operation of the system in accordance with the presentdisclosure. The system generally is directed toward a capture device 102that is operable to capture, in this embodiment, an image of anindividual; for example, the individual denoted by the reference numeral104. This can be any type of scene or any type of information that iscaptured. This could be a video segment, a still picture or an audiosegment. It should be understood that the capture device 104 couldcapture any type of information, not just video information. As will bedescribed herein below, the purpose of the system of the presentdisclosure will be to not only capture information but to store theinformation in a secure and certifiable manner such that it isnon-repudiable. The capture device is controlled by a user through aninput/output (I/O) interface 106. The image 104, in this example, willbe captured in the form of a capture file 108 stored in a storage area110, this being a buffer area. The capture device 102 could be a cellphone that has a video camera associated therewith, any type of devicehaving a digital camera associated therewith, an audio system forcapturing an audio file, etc. The phone, in one example, can capture anddigitize the image, or even a video segment.

Once the captured image 108 is formed and temporarily stored, it thengoes to the next step of the operation. In this step of the operation, aprocess block 112 is provided to obtain local certification. Localcertification, in this example, is some certification that is viewed asproviding information in such a manner that there is a high level ofconfidence in that information which is to be associated with the imageas an integral part thereof and will, as described herein below, followthe image. For example, the information that is obtained will be timeand date information and longitude and latitude information that isreceived from a GPS system (global positioning system), a conventionalsystem. The time information, the date information and the longitude andlatitude information are provided in such a manner that, when associatedwith the capture file 108, this provides some current validation thatthe file was created at that particular time and, at a later time, itcould be identified by the fact that it has that information associatedtherewith. For example, a user could make a log, either printed orelectronic of the image captured and, at a later time, by merely knowingwhat the time and data information was and the longitude and latitudeinformation was, this would provide a higher degree of confidence thatthe later viewed file and the original captured file was the same andhad not been tampered with or had not been reproduced at a later timeand location.

In order to provide this verification, the trusted entity is the GPSsystem, since this is a system that provides a time stamp and alongitude and latitude from the calibrated system. If this isimplemented in such a manner that it is an integral part of the captureoperation, i.e., it is integrated into the phone, for example, then ahigh degree of confidence is maintained that this was obtained basicallyat the time the capture was complete. The GPS system, as noted hereinabove, is a conventional system that utilizes a GPS receiver 114 thathas an antenna 116 that is operable to receive information from aplurality of satellites 118. Typically, there can be anywhere from threeto ten or more satellites from which information can be received toobtain an accurate location. Alternate techniques for recovering time,date and position information includes differential and Doppler analysisof very precise timing signals coming from a plurality of cellular/PCSbase stations. A third technique for recovering time, date and positioninformation includes retrieving information directly from the MobilityManagement (MM) sub layer of the cellular protocol, where the mobiletelephone service provider is a party to the transactions. Finally,another technique of retrieving accurate time and date informationinclude use of a network time server.

The result of the local certification is a locally certified capturedimage 120 which is illustrated with the image and a time stamp, “TS,”disposed on the edge thereof, this location by way of example only, asother methods of disposing this information are described herein below.This “TS” indicates that there is some information that is “embedded”into the captured file or captured image that is now part of the file.For example, as will be described in more detail herein below, there isa science of embedding information referred to as “Steganography” thatallows information to be embedded in some expression of intellectualproperty (a photograph, a musical recording, or other expression,) suchthat (a) the information is hidden from casual observers and (b) theinformation is not easily altered or destroyed. One such type is a“water mark” that basically is disposed in the background of a document,for example. In images, there are encoding techniques such as “glifs”that can be disposed in the image which is an optical type encoding thatappears as a random background to a viewer, but actually containsdigitized information. The result is that the document, file image,etc., is indelibly marked with the date, the time and the location, inaddition to associating therewith information about the user in the formof a user ID, which is provided in a user ID block 122. The localcertification block 112, therefore, is operable to merge the capturedfile 108, the GPS information as to time stamp and location and the userinformation into the single document 120. At this point, the document120 is still a “clear” document such that it can be viewed by anyindividual. The image 120 is stored in a temporary image buffer 121.

After the document 120 has been created with the local certification,the system then compresses the file using any of a number of well-knownmethods. In the case of an image, the compression technique may be alossy algorithm such as JPEG or (in the case of motion pictures) MPEG,or for a data set, the compression technique may be a lossless methodsuch as Lempel-Ziv-Welch.

After compression, the file 120 is processed through an encryptionoperation wherein the file is first encrypted in accordance withpredetermined encryption algorithms, this being performed in a block124. The encryption, as will be described herein below, is a doubleencryption operation which wraps the local certified captured file witha first level of encryption 126 and a second level of encryption 128 toprovide an encrypted document 130. This is then stored in a temporarystorage buffer 132. The file 130 is then subjected to a non-repudiationcertification process to acquire a Certificate of Authenticity (CA) froma certification authority 135, this certification authority 135 being atrusted third party that can “digitally sign” a file, image, etc. andprovide a level of authenticity to that file. This is conventionaltechnology. The document 130, in its encrypted form, is converted to a“hash” file and this hash file, which is a representation of theencrypted file, is sent to the certification authority 135 via atransmitter and antenna 136 along a wireless path, and received by anantenna 137 at the certification authority 135 location. Again, this isa wireless operation. The hash file is then signed and a combinationhash file and certificate of authenticity is then sent back to theantenna 136 which is then stored in a temporary memory 133 as acertified document. This is illustrated with the attached certificationauthority certificate 139. This is the file that is sent to the securestorage facility, this being a file 130′.

After encryption, certification by the CA and compression, the encryptedfile is then passed to the transmitter 134 for transmission via theantenna 136 along a wireless path to a secure storage facility 138having a receiving antenna 140 associated therewith. The secure storagefacility 138 is a repository. In one embodiment, this repository 138does nothing more than to store the image 130 in a large database 142for access at a later time. Additionally, the secure storage facility138 could be a trusted storage facility, which trusted storage facilityhas the ability to “unwrap” the encryption from the document 120 suchthat it can transmit the document 120 at a later time upon request.Alternatively, the secure storage facility 138 could merely be a placeto store the information with secure measures as to restricting accessto only authorized individuals. In that scenario, the secure storagefacility 138 would not be able to decrypt the image 130 and would merelybe able to transfer the image to the individual or entity authorized toaccess that information.

For access, a remote access site 144 is operable to send requests to thesecure storage facility 138, identify themselves with the appropriatepasswords to comply with the security procedures of the secure storagefacility 138 and then have the image requested sent thereto. This imagecan then be stored in a memory 146 and decrypted with a decryptionalgorithm in a block 148 for storage of the decrypted file 120 in astorage space 150. This can then be extracted by a user for whateverpurpose. In general, all of the encryption ensures that there has beenno “tampering” with the file before it is decrypted. Once decrypted,then the time date stamp and location information, in addition to theuser information, is still embedded in the picture, document, audiofile, etc. that makes up the captured file to show that there was somelocal indelible certification that verifies the captured file as beingauthentic and which was embedded at the time of creation.

Referring now to FIG. 2, there is illustrated a diagrammatic view of thecaptured and encrypted file 130 which, as noted herein above, iscomprised of the locally certified captured file 120 wrapped by thefirst layer of encryption 126 and the second layer of encryption 128. Aswill be described herein below, the first layer of encryption is asymmetrical encryption algorithm and the second layer 128 is anasymmetrical encryption layer 128. The symmetrical encryption layer issomething that can be unwrapped merely by having access to variouspublic keys. This is a fairly conventional PKI system. The second layerof encryption, the asymmetrical encryption layer, is a layer thatrequires a private key in order to extract this layer. Therefore, inorder to gain access to the file at the second layer of encryption, theindividual must have the private key to unwrap the first layer and theother key to unwrap the second layer. Again, this will be described inmore detail herein below.

Referring now to FIG. 3, there is illustrated a flow chart depicting theoverall operation of the capture operation, which is initiated at astart block 302 and then proceeds to a function block 304 in order toallow the user to activate the capture device 102. The user activatesthe capture device 102 and then a capture operation is initiated at ablock 306. Upon initiation of a capture, there is, in one embodiment, a“start” request sent out to the certification authority 135. Thecertification authority 135 receives the request generated at the block308 for a certification certificate as to the “start” information thatwas sent to it. This can merely be the text “start” that is certified.This is sent back to the system during the capture operation. A decisionblock 310 indicates that this operation which will wait for the receiptof the certificate. However, during the time that this certificate isbeing generated, the capture is continuing. Once the program, after thestart request is generated, then flows to a decision block 310 to waitfor the completion of the capture operation. As soon as this iscomplete, the program flows along a “Y” path to a function block 312 inorder to request the time, date, longitude, latitude information andthen embed this information along with user information, as indicated bya function block 314. This is embedded into the captured file asdescribed herein above. The program then flows to a function block 316in order to request a “stop” certificate from the certificationauthority 135. In this operation, the certificate is requested prior toencryption such that the “clear” file can be certified prior toencryption with the certificate 139. However, the file could beencrypted first and then certified. The program then flows to anencryption block 318 to encrypt the file and then to a function block320 to compress the file. This compressed file is then transmitted tothe repository, as indicated by a function block 322 and then theprogram proceeds to an End block 324.

Referring now to FIG. 4, there is illustrated a flow chart depicting theoperation of the request operation for the start certificate, asinitiated at a block 402. The program then proceeds to decision block404 in order to initiate the capture operation. When the captureoperation is initiated, the program flows along a “Y” path to a functionblock 406 to send the “start” text to the certification authority 135.Of course, this could be a “hash” of a certain initial part of thecapture file, but just the text would be sufficient. The program thenflows to a decision block 410 to determine if the certificate has beenreceived for this “start” text and, when it has been received, theprogram will flow along the “Y” path to a function block 412 to storethis received certificate in association with the captured file. Ofcourse, this may not be disposed in association therewith until thecapture is complete. Additionally, although not illustrated in this flowchart, the start time could also have time and date information as wellas longitude and latitude information associated therewith such thatthere would be local certification of both the start time and the stoptime which is received from a trusted authority, i.e., the GPS system.Once this information is determined as stored in association with thecaptured file, the program flows to a return block 414. Again, thisinformation may merely be stored in a temporary buffer until the captureis complete.

Referring now to FIG. 5, there is illustrated a flow chart depicting theoperation of requesting information from the GPS, which is initiated ata block 502. The program then flows to a function block 504 in order toaccess the GPS system. This, again, is a conventional operation whichwill obtain both accurate time information and location information.This access of information is indicated in a function block 506. Theprogram then stores this information and flows back to a Return block508.

Referring now to FIG. 6, there is illustrated a flow chart depicting theoperation of embedding information into the captured file, which isinitiated at a block 602. The program then flows to a function block 604to initiate a steganography algorithm. The steganography operation isoperable to permanently modify the captured file with the time/dateinformation and longitude and latitude information as well as user IDinformation, this indicated at a function block 606. The program thenflows to a function block 608 to store a modified captured file withthis local certification information embedded therein. Again, this localcertification information provides some level of authenticity to a“clear” file. The program then flows to a Return block 610.

Referring now to FIG. 7, there is illustrated a function block or a flowchart depicting the operation of requesting the stop certificate, whichis initiated at a start block 702 and then proceeds to a function block704 to create the “hash” file of a modified capture file. This hash fileis then sent to the certification authority 135, as indicated by afunction block 706. The program then flows to decision block 708 to waitfor the receipt of the certificate and, once received, flows to afunction block 710 to basically sign the modified capture file andassociate with the modified capture file a certificate of authority.Since the hash file is a digital representation of the actual capturedfile, the actual capture file does not have to be transmitted to thecertification authority 135. The reason for this is that one would liketo prevent the transmission over any wireless link of “clear”information. As such, the hash file has no discernable informationassociated therewith and, as such, it only has meaning when associatedwith the original file from which it was generated, since the algorithmfor generating a hash file will clearly identify the two. As such, thecertificate generated by the certification authority 135 is sufficientto ensure that a trusted authority has in fact verified the authenticityof the file, this indicated by a function block 712 wherein the capturedfile is signed and then the program flows to a Return block 716.

Referring now to FIG. 8, there is illustrated a flow chart depicting theencryption algorithm operation, which is initiated at a block 802 andthen proceeds to a function block 804. This is the operation whereinsymmetrical encryption is utilized with a “public and private keysystem.” The symmetrical encryption is an operation in which a plaintextmessage is transformed by a well-known algorithm operating under controlof a key. The key is a short (less than 1000 bits, usually) data stringthat instructs the encryption algorithm how to transform the plaintextinto an unreadable form called ciphertext. This type of encryption iscalled “symmetrical” because the same key that is used to encrypt theplaintext is used to decrypt the ciphertext, resulting in a plaintextfile once again.

After encryption in the “first layer,” the program then flows tofunction block 806 to create the first ciphertext file. This firstciphertext file is then processed with an asymmetrical encryptionalgorithm, as indicated by a function block 808 to further encrypt orprotect the captured file. The second general type of cryptosystem isasymmetrical encryption. This encryption scheme uses mathematicalfunctions called one-way or trapdoor functions that are easy to performbut extremely difficult to reverse. Examples of these one-way functionsare factoring large composite numbers (two large numbers are easy tomultiply, but finding the two large numbers given the product alone isdifficult) and the discrete logarithm problem (raising a number to apower modulo some value is easy, but finding the number given the resultis difficult). In an asymmetrical cryptosystem, one key (referred to asthe public key) is used to encrypt the plaintext and a second, relatedkey (called the private key) is used to decrypt the ciphertext. In apublic-key encryption scheme, it is common to publish the public key. Inthis way, anyone can send a secure message, but only the holder of theprivate key can decrypt the message and reveal the plaintext.

Asymmetrical cryptosystems have another use as well: by encrypting afile under his or her private key, a party can prove that he or she isthe author of the message. If others can decrypt the file using theassociated public key, then nobody but the holder of the private keycould have created the message. This leads to properties favorable tothe present invention: proof of ownership and non-repudiation. Theresult of the asymmetrical encryption step will be the creation of thesecond ciphertext file as an encrypted stamped and certified capturedfile, as indicated by function block 810. The program then proceeds to aReturn block 812.

To illustrate how the system of the present disclosure operates, oneexample of an application of the capture device 102—a wireless digitalcamera—will be described.

The user takes a picture, video, audio, or acquires any other data set,or any combination of these. The apparatus then sends a request to acertificate authority to obtain a certification of the time and date ofthe recording. This certificate, as well as time, date and locationinformation obtained from the GPS receiver or other techniques fordetermining this information, as well as an identifying number unique tothe wireless digital video camera, is steganographically encoded ontothe image and/or audio files.

The image is now marked, but it is still “in the clear.” That is, anyonewho gains access to the image file will be able to reproduce the image.It must now be secured so that unauthorized parties cannot view theimage.

After compression, the next step is to encrypt the file in such a waythat the file cannot be used without access to a secret key.

Once the image file has been indelibly marked and compressed, and it isabout to be encrypted using a symmetrical cryptosystem, a decision mustbe made as to what key to use. There are several methods of establishinga key. The first is to have a single, fixed key assigned to the wirelessdigital recorder (i.e. camera) at the factory. The problem with thismethod is that if this key becomes compromised, then all images taken bythe wireless digital recorder (i.e. camera) are compromised. A secondmethod is to create a new, random key each time a photograph is taken,and store the table of keys in the wireless digital recorder (i.e.camera) for subsequent download. This, although feasible, may beundesirable for the same reason that storing the images themselves inthe wireless digital recorder (i.e. camera) is undesirable: memory inthe wireless digital recorder (i.e. camera) is fragile, and if the keysare lost, the images are useless.

Instead, a preferred method of key management is used. In this scheme,the serial number of the wireless digital recorder (i.e. camera) andother pertinent information that can be recovered without recovering thefile (like the filename, the time and date, etc.) are securely hashed.Hashing refers to a practice of creating a short dataset that representsa larger dataset. For example, if one were to assign all the letters ina document a number (A=1, B=2, etc.), add those numbers together modulo26, one would come up with a single number between 0 and 25. If anyletter in the document changed, the result of the function would changeas well, and thus could be used as an indication that the document hadchanged. In a way, the short dataset (the modulo sum) would stand in forthe larger dataset (the document). Note that the short dataset cannot beused to reproduce the document, but that changing the document in a waythat doesn't affect the modulo sum is difficult.

Hashing works in just this way, but with much larger numbers. In thedisclosed system, the serial number is hashed with other information tocreate a key. If the key is compromised (by technical or legal means)then no other photograph taken by the wireless digital recorder (i.e.camera) is compromised. It is impossible—not just difficult—to go fromthe hashed key to the source material, in the same way it is impossibleto deduce this document from one modulo sum character.

Now the file is encrypted, and only the holder of the secret key canunlock the file. Two more steps remain before the file is transmitted tothe secure storage facility. First, the entire encrypted file is passedthrough a message authentication algorithm, which produces a hash(similar to the way the symmetrical encryption key was calculated,above) over the whole file. In this way, if any byte of the message fileis corrupted in transmission, it will be discovered. The file is thenencrypted using an asymmetrical cryptosystem under the user's privatekey, effectively signing the file.

Finally, identifying information is added to the (now doubly) encryptedfile, and the file is encrypted again—this time, under the storagefacility's public key. Now, observe the properties of the file thuscreated:

-   -   The file is secure. Nobody but the storage facility can open the        outer wrapper.    -   The file is anonymous to casual observers. There is no        identifying information outside of the outer wrapper.    -   The file is signed. The storage facility can open the outer        wrapper and discover an identifier of the party who claims to        have created the file.    -   The signature is irrefutable and cannot be repudiated. The        storage facility can look up the public key of the party        claiming to be the author of the file, and can attempt to open        the middle wrapper. Inside, they will find an encrypted file and        a hash of the file. If the calculated hash matches the given        hash, then the photograph without question belongs to that        party.    -   Even after two wrappers have been removed, the picture is still        secret. The storage facility keeps only encrypted files. They        have no means of removing the final wrapper.

Should it become necessary to prove the authenticity of the photograph,the storage facility 138 can testify to all the above facts.Additionally, the originator of the photograph is the only one who canunlock the inner wrapper and produce the photograph. Finally, thephotograph itself is steganographically marked, and this finalinformation is clinching proof that the provenance of the photograph isaccurate.

To return to the example wherein the picture is ready for transmissionat this point, the wireless digital recorder (i.e. camera) attempts toconnect to the server at the secure storage facility 138 or otherrecipients who have access the network (i.e. PDA's, other wirelessdigital devices) using any of a number of well-known wireless methods.Among these are data channels associated with IS-95 CDMA, IS-136 TDMA,CDPD, GSM as well as purely data paths such as 802.11b. The exactmechanism of data transmission is not germane.

However the data is transmitted, the storage facility 138 receives thetriply-encrypted data file and performs the following steps:

-   -   Remove the outer wrapper and extract an encrypted file and        plain-text subscriber identification.    -   Look up the subscriber information and recover his/her public        key.    -   Remove the middle wrapper using the public key to reveal an        encrypted file and a hash value.    -   Pass the encrypted file through a message digest algorithm to        produce a computed hash.    -   If the computed hash does not match the received hash, send a        negative acknowledge and discard the file; otherwise . . .    -   Calculate a message digest of (1) the received hash, (2) the        time and date, and (3) a random number.    -   Return an affirmative acknowledgment and a certificate        containing the message digest calculated in (6), above.    -   Store the encrypted photograph along with the received time and        date and the random number produced in (6). In this way, if the        certificate is ever challenged, the storage facility will be        able to verify that it sent the certificate.

The user can also transmit these files over various networks to otherrecipients (PDA's, cell camera phones, “IP Addresses, E-mail to name afew) for their review and storage. However the users' unique identityand other certificates described in this document are embedded withinthe file(s).

The wireless digital recorder (i.e. camera), upon receipt of thecertificate, transmits an acknowledgment and removes the photograph fromits temporary store. The certificate can be stored or discarded—it isnot required to retrieve the photograph. If stored, it becomes furtherevidence of the provenance of the photograph.

Image retrieval from the storage facility 138 is simple. At login, thestorage facility presents a random string encrypted under the user'spublic key. The user must decrypt the string and re-encrypt it under thestorage facility's public key. Only the holder of the secret key can dothis and it proves beyond doubt to the storage facility that they arecommunicating with the owner of the photograph.

Once identity is established, the user can download any file from thestorage facility. Once downloaded, the user can open the final wrapperand extract the image.

Again, this works for any kind of media file—photographs, images, music,audio spoken word, video, physical phenomena—anything. An obviousapplication would be in “black boxes” embedded in transportationfacilities. Following an accident, information could be transmittedusing the above schemes to a storage facility. Only authorized personnelcould then retrieve the encrypted messages and return the data tocleartext form.

With the disclosed system, this provides for a method of storing,cataloging, viewing, playback and printing of images, video, audio andphotographs change as well. Instead of relying on photo finishers,anyone with an inexpensive printer can reproduce images, anyone with aCD reader/writer can reproduce audio, and anyone with a DVDplayer/recorder can reproduce both images and audio.

Additionally, instead of a fireproof safe, image, video, audio andphotograph storage involves digital media. And, instead of couriers andthe mail, transmitting images, video, audio and photographs from oneplace to another is likely to involve the Internet.

This new world of opportunities has its problems as well. Once images,video, audio and photographs are in the digital domain, there areopportunities to modify these so that it no longer represents the eventsthat actually occurred. Digital cameras or other digital recorders atthe time of this submission, typically include a clock of dubiousaccuracy that can, in any event, be set back or forward to make it seemas though an event occurred at a time other than the actual time of theevent. And the metadata—the time, date, and location of the images,video, audio and photographs—is not stored using any secure method.Anyone knowledgeable in the field can modify the metadata to make theimages, video, audio and photographs appear that it was taken at a timeand place other than the real time and place.

Another problem solved with the system of the present disclosure is thatof storage. For many users (photographers, musicians, forensic,video/audio personnel, governmental, military personnel, public service,professional and non professional personnel and others) the value of theimages, video, audio and photographs taken far exceeds the value of theequipment used to take them. For these users, it is important that theimages, video, audio and photographs themselves be transported to asecure location at the earliest possible opportunity. Digital recordingdevices (i.e. digital cameras and other digital recording devices) relyon memory cards that contain non-volatile solid-state memory that, whilerobust for a solid-state device, is easily damaged by mechanical shockor static electricity. Unlike film, in which a defect may only cause aminor blemish in the image, a single defect in the memory card of adigital recording device may be enough to render all the information onthe card useless.

It is noted that the images, video, audio and photographs not bedisclosed to an unauthorized third party. While traditional analog filmimages, video and audio recordings can be physically locked into asecure facility, digital images, audio, and video reside on computers.These computers can be the subjects of network attacks and informationon them can be compromised in two ways. First, a knowledgeable opponentcan read information from an internet-connected computer—that is, anopponent can view images, video, audio and photographs he or she isunauthorized to view. Second, a knowledgeable opponent can obtain writepermission and modify the images, video, audio and photographs in a waythat is difficult to detect.

Finally, the user is provided the ability to attach, mix, and modifymedia files easily and indelibly mark each image, video, audio,photograph or media file as his or her own work, to eliminate thepossibility of plagiarism and to provide a certificate authority whilewirelessly transmitting said media files for secure storage or toanother recipient or source.

In the days of film cameras (analog), security usually meant placing thenegatives into a photo safe. Prints made from the negatives could bemarked with an identifier that clearly indicated the pedigree of thephotograph. Those who would use the photograph without permission of theowner would be subject to a copyright infringement suit—and it would besufficient evidence in court for the user to produce the negatives andtestifies that, in fact, he or she took the photographs.

With the advent of digital media and the proliferation of the Internet,images, video, audio, photographs and other forms of digital documentsstored on digital computers are no longer secure.

This invention addresses all of these concerns. It provides a mechanismfor recording, attaching, mixing, appending to, modifying images, video,audio and photographs, marking the images, video, audio and photographsindelibly with a provable time, date, location and identity of theindividual taking the images, video, audio and photographs. It thenprovides a means to transport the images, video, audio and photographsto a secure, off-site storage facility and to obtain positiveconfirmation that the transmission occurred error-free. It provides amethod for securely rendering the image, video, and audio and photographuseless to anyone but the original user. Finally, it provides theability to demonstrate, with legal certainty, that the image, video,audio and photograph was taken at the location and at the timeindicated, and that the image or audio file has not been altered, aswell as, tracks ongoing changes made by the originator or other useridentities within the original file.

Although the preferred embodiment has been described in detail, itshould be understood that various changes, substitutions and alterationscan be made therein without departing from the spirit and scope of theinvention as defined by the appended claims.
